Photo of rumored 4-inch iPhone leaked online

Apple blog One More Thing has leaked an image of the widely-anticipated new 4-inch iPhone model. The smaller iPhone variant will likely be unveiled by Apple -- in coincidence with the launch of an upgraded Apple Watch edition -- at an event scheduled to be held in March.

The photo leaked online by One More Thing is supposedly the image of a prototype of Apple’s forthcoming 4-inch iPhone. The leaked photo shows the 4-inch iPhone next to an older, similarly-sized variant of iPhone 5.

Though the 4-inch iPhone model underscores a smaller form factor of the iPhone, it will probably boast the inclusion of a number of noteworthy specifications of the 4.7-inch version of iPhone 6 launched in 2014. Some of the expected features of the 4-inch iPhone include Apple’s A8 processor; barometer sensor; NFC chip; an 8-megapixel back camera; and a 1.2-megapixel front camera.

In addition, the new 4-inch iPhone will have curved edges -- similar to those of iPhone 6 -- instead of the sharp rectangular edges of the iPhone 5 and iPhone 5S models; and will boast support for the Apple Pay mobile payment platform.

Meanwhile, according to a 9to5Mac report, the new 4-inch iPhone will probably be called iPhone SE, with the ‘SE’ in its name apparently standing for ‘special edition’ of iPhone 5S.
